Case IH builds some of the heaviest tractors working American farmland — row-crop machines that carry large implements and pull hard through tough conditions. That work puts real strain on the 3 point linkage, which is exactly why quality replacement parts matter for Case IH owners. And because Case IH builds its hitches to the standard ASAE S217 / ISO 730 dimensions, replacement parts are interchangeable across brands within the same category.
Jrs Farm Parts is an ISO 9001:2015-certified manufacturer in Ludhiana, India, exporting tractor linkage parts to the USA and 60+ countries. We manufacture top link assemblies, pins, balls, and stabilizers for the hitch categories Case IH tractors use.
Important: Jrs Farm Parts is an independent manufacturer. We are not affiliated with, endorsed by, or connected to CNH Industrial or Case IH Agriculture. “Case IH” is used here only to describe general compatibility with Case IH tractors.
Which Hitch Category Does Your Case IH Use?
Case IH’s lineup spans compact, utility, and heavy row-crop classes. Use this as a starting point — always confirm against your tractor’s operator manual.
| Case IH Family (General) | Typical Hitch | Notes |
|---|---|---|
| Compact models (Farmall compact range) | Category 1 | 3/4 in (19 mm) top link pin |
| Utility models (Farmall utility, Maxxum range) | Category 2 | 1 in (25 mm) top link pin |
| Large row-crop (Magnum, Steiger ranges) | Category 2 / 3 | Large Magnum and all Steiger models use Cat 3 — check pin diameter |
Quick check: measure the top link pin diameter. 3/4 in = Category 1; 1 in = Category 2; 1-1/4 in = Category 3. If in doubt, confirm in your operator manual before ordering.
Case IH Linkage Parts We Manufacture
Top Link Assemblies
The top link carries the top connection point and controls implement angle — under heavy draft loads on large implements, a quality top link matters. Our top link assemblies come with forged ball ends and UNC-thread center tubes in Category 1, 2, and 3 sizes, with telescopic and ratchet-jack variants for easier adjustment.
Pins and Retaining Hardware
Hitch pins, top link pins, lower link pins, linch pins, and clevis pins secure every connection. For large row-crop implements, pins carry serious shear loads — our heat-treated pins are available across the diameters Case IH-category hitches use, in bent-handle, fixed-handle, and temple-handle styles.
Linkage Balls
Lower link balls and top link balls take constant load and wear at every pivot. Our hardened balls (58–62 HRC, in grades such as 16MnCr5) are manufactured for the bore sizes used on Category 1, 2, and 3 lower links — the heavy-duty replacement for worn ball ends.
Stabilizers and Leveling Assemblies
Stabilizers keep wide implements centered during transport and field work — critical on large row-crop tractors. We manufacture chain stabilizer assemblies with turnbuckle adjusters and ratchet-jack stabilizers for Category 1 and 2 tractors, plus leveling assemblies for the adjustable lift arm.
Buying for Dealers and Distributors
Case IH dealerships serve a mix of compact owners and large row-crop operators. The stocking pattern differs from compact-focused brands:
- Category 2 utility parts — steady movers for Farmall utility and Maxxum owners
- Category 3 large row-crop parts — lower volume but high value per sale
- Category 1 for compact Farmall models
We sell wholesale to dealers, distributors, and agricultural parts suppliers. Factory-direct pricing, ~40-day export lead time, and ISO-managed quality make us a dependable supply source for the US market.
Verify Before You Order
Our parts are engineered to the standard ASAE/ISO dimensions for each category. Because Case IH models vary, we do not guarantee fitment for any specific model — always measure the pin diameters and link spacing on your tractor and confirm the part matches before ordering. If you are unsure, send us photos with a ruler for scale and we will help identify the right part.

Frequently Asked Questions
Are these genuine Case IH parts?
No. Jrs Farm Parts manufactures aftermarket replacement parts to standard ASAE/ISO Category 1, 2, and 3 dimensions. They are designed to interchange with OEM components but are not manufactured by CNH Industrial.
Will this top link fit my Case IH model?
If your Case IH uses a standard Category 1 or 2 hitch, the matching category part fits the standard dimensions. Because models vary, always measure your top link pin diameter and confirm the category before ordering — we do not guarantee fitment for any specific model.
How do I know which category my Case IH uses?
Measure the top link pin diameter with a caliper: 3/4 in = Category 1, 1 in = Category 2, 1-1/4 in = Category 3. Your operator manual will also state the hitch category.
Do you offer UNC and metric thread options?
Yes. Top links and top link ends are available in UNC (UNCR/UNCL, standard for North American tractors) and metric (M22-M30) threads.
Do you supply dealers and distributors?
Yes. We supply wholesale to dealers, distributors, and agricultural parts suppliers in the USA, with factory-direct pricing and standard export terms.
